Abstract (en)

The invention relates to an inertial sensor comprising a substrate extending along a rotation direction and a drive excitation direction, a first and a second drive frames, an excitation device, a first and a second proof mass hingedly connected to the first and second drive frames along a first and a second connection axis respectively, a lever pivotably mounted around a fulcrum axis, strain gauges mechanically stressed by the lever when said lever is rotating around the fulcrum axis, wherein the first proof mass is rotationally connected to the lever along a first coupling axis, the second proof mass is rotationally connected to the lever along a second coupling axis, the first connection axis is further away from the fulcrum axis than the first coupling axis, the second connection axis is further away from the fulcrum axis than the second coupling axis.
